When hooked up to an air supply on one end, and your valve stem on either chuck, you can simply depress the lever on the handle to start the inflation.

It should only dis-charge air out one outlet or the other. If it's dis-charging air out of both outlets at the same time then 2 things could be happening. 1. inflater could be faulty from the factory or from being abused somehow. 2. sometimes debrie (sand,dirt) will get in the outlet & keep the core from closing, thus a good cleaning might remedy this. Both outlets has a core in them that works somewhat like the core in a valve stem in a tire.
